GRATE-BAR.

SPECIFICATION forming part of Letters 1 8.156.1117 N0.-282,192, dated July 31, 1883. 1

Application filed May 121883. (No model.)

To 0% whom it may concern:

Be it knownthat I, WILLIAM HENRY HEE- soN, of Dudley, in the county of Huntingdon and State of Pennsylvania, have invented certain new and useful Improvements in Grate- Bars; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which.

Figure 1 is a perspective view of my improved grate. Fig. 2 is a cross-section online we, Fig.1. Fig. 3 is a perspective view of one of the. grate-bars; and Fig. 4 is a cross section, on an enlarged scale, of the same.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to that class of grate-bars which are pivoted at their ends" middle rib, which pass across the upper edges of the ribs, as hereinafter more fully described and claimed. 7

i In the accompanying drawings, the letter A indicates the central longitudinal rib, which extends the entire depth of the bar, and the ends of which form trunnions, which rest and turn in bearings B inthe frame which supports the grate; and 0 represents the ribs,

which extend laterally from both sides of the L web, alternating with each other, and having their upper edges, D, cut off slanting to both sides, and the'lower portions of the side edges cut ofl slanting in'toward the central web. The ribs of one bar fit into the interstices between the ribs of the bar, turning at the side of it, with their outer ends, so that the cinders and coke which collect upon the grate will be clipped between the ribs when the bars are shaken; and to give the upper edges of the ribs a better bite upon the cinders,they are notchedtransversely at E,formingl0ngitudinal grooves in the upper surface of the entire bar, one notch being upon each sideof the central rib, which notches will assist in grasping the cinders and hold them when the bars are rocked, forcing them to be crushedbetween the ends of the ribs and fall between the bars into the ash-pit." The bars are providedupon the lower edge of the central web, at one end, with two perforated lips, F, between which a transverse bar, G, is hinged, which bar 0011- nects the several bars, so that when one of the grate-bars is rocked by a crank or similar means attached to the rounded end of the same, the other bars will be rocked simultaneously in the same direction. Inthis manner( it will be seen that the cinders will be thoroughly broken and ground small by shaking the bars, whereby the cakingand burning of the grate-bars will be prevented, which is liable to happen when the cinders cannot be broken up fine, so that they are permitted to stay upon the grate and burn and cake upon.

the same.

Having thus described my invention, I claim and desire to secure by Letters Patent of the 'United States- The herein-described grate-bars, consisting of a central longitudinal web pivoted at both ends, and having alternating laterally-extend ing ribs, having their upper edges cut off slantingly, and notched upon both sides of the central web, and provided with a connecting-bar hingedto the lower edges of the grate-bars, in combination with means for rocking the bars, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

WILLIAM HENRY HEESON.
